Isolated thunderstorms will pepper San Antonio Thursday before more sustained rainfall affects the area over the weekend, according to the National Weather Service.

The rain started falling in the Alamo City area around 7 a.m. and is expected to continue throughout the day, possibly picking up towards the afternoon.

Forecasters aren't expecting much rain Thursday, but with the soil already so saturated from the past two weeks of rainfall, minor flooding is possible.

"It won't take a whole lot of additional rainfall to cause some issues," said Brett Williams, a meteorologist with the National Weather Service.

The storms are the result of tropical moisture from the gulf coast pouring into South Central Texas and mixing with eastbound upper-level disturbances.

The greater cause for concern will come this weekend, when sustained storms could drop up to 4 inches of rain in San Antonio.

"Things should really start getting going Friday and continuing through the weekend," Williams said.

Temperatures are expected to remain steady in the mid to upper 80s.
